Commemorates the apparition of the Blessed Virgin Mary to three children in Fatima, Portugal on the 13th of each month from May to October in 1917. Our Lady appeared to Lucia, age 9, BlessedFrancisco Marto, age 8, and BlessedJacinta Marto, age 6, while they were tendingsheep; they described her as “a woman all in white, more brilliant than the sun”, and her message was to do reparation for sins that offend God, and to pray constantly for the conversion of sinners. She asked for devotion to the Holy Trinity, and for praying the Rosary daily for world peace. Word spread, and by the final apparition on 13 October, 70,000 people showed up to witness the Lady and the sign that she had promised; they witnessed the sun make three circles and zigzag around in the sky.
